COMMONWEALTH ELECTORAL DIVISIONS
Commonwealth Electoral Divisions (CED) are an ABS approximation of the Australian Electoral Commission (AEC) electoral division boundaries. An AEC electoral division boundary is an area legally prescribed for the purpose of returning one member to the House of Representatives, Australia's Federal Lower House of Parliament. Boundaries are based upon the AEC electoral division boundaries current on Census Night 9 August 2011. CEDs may change as the AEC revise their boundaries. Where the AEC revise their boundaries, the CEDs will be updated on an annual basis in July in conjunction with updates of other Non-ABS Structures.
More information can be found on the Australian Electoral Commission website: http://www.aec.gov.au
METHODOLOGY
The boundaries and census statistics produced for CEDs are constructed from Statistical Area Level 1 (SA1) based on the method described in Chapter 1.
CEDs are based on publicly available versions of AEC electoral division boundaries. 168 CEDs are defined to cover the whole of geographic Australia. CEDs do not generally cross State and Territory (S/T) borders but there are two exceptions. Jervis Bay Territory is included in the Australian Capital Territory electorate of Fraser and the Territories of Christmas Island and Cocos (Keeling) Islands are included in the Northern Territory electorate of Lingiari. CED boundaries are generally different to State Electoral Divisions (SEDs).
No Usual Address and Migratory-Offshore-Shipping are represented as non spatial objects in the digital boundaries.
CED NAMES
CED names are the same as those allocated by the Australian Electoral Commission.
CED CODING STRUCTURE
CEDs are sorted by name then allocated a two digit code starting from 01 within each S/T. This is prefixed by a single digit S/T code to enable unique identification of CEDs across the country.
Special purpose codes are included as balancing items. SA1s allocated to these codes are not part of any official CED.
• CED code 94 is reserved for those S/T where people are coded to the No Usual Address SA1s.
• CED code 97 is reserved for those S/T that have Migratory, Off-Shore and Shipping SA1s.
Example:
| S/T Name | S/T Code | CED code | CED Name |
|
| South Australia | 4 | 401 | Adelaide |
| South Australia | 4 | 402 | Barker |
| South Australia | 4 | 403 | Boothby |
| South Australia | 4 | 404 | Grey |
| South Australia | 4 | 405 | Hindmarsh |
| South Australia | 4 | 406 | Kingston |
| South Australia | 4 | 494 | No usual address (SA) |
| South Australia | 4 | 497 | Migratory - Offshore - Shipping (SA) |
|
CEDs are renumbered after each census therefore the codes allocated for the 2011 Census may not match those used for the 2006 Census.
